Communication device and method of controlling based on wireless communication environment

ABSTRACT

Apparatuses, methods, and systems for providing control information to a communication device are described. In the method, it is determined whether a communication device has received device control information from a central management server (CMS) while in a first wireless communication environment, where the device control information is for controlling the communication device in a second wireless communication environment. If the device control information is received while the communication device is still in the first wireless communication environment, the communication device uses the received device control information when in the second wireless communication environment.

PRIORITY

This application claims priority under 35 U.S.C. § 119(a) to Korean Patent Application Serial No. 10-2015-0150166, which was filed in the Korean Intellectual Property Office on Oct. 28, 2015, the entire contents of which is incorporated herein by reference.

BACKGROUND

1. Field of the Disclosure

The present disclosure relates generally to a communication device and a control method thereof and, more particularly, to controlling a communication device based on its own moving pattern, control information according to the moving pattern, and a control method thereof.

2. Description of the Related Art

Wireless communication systems provide high-speed data communication as well as various multimedia services. The Long Term Evolution (LTE) wireless communication system, which was proposed by the 3rd Generation Partnership Project (3GPP) standard group, provides services in multiple countries. The LTE system is a technology which implements high-speed packet based communication providing a transmission rate of about 100 Mbps. Presently, efforts are being made with regard to future communication systems, i.e., after (beyond) the 4G network and the LTE system, systems which improve the transmission rate by combining various new technologies with LTE or LTE-Advanced (LTE-A) systems.

In order to operate, a communication device such as a User Equipment (UE), the UE measures and collects pieces of information related to its wireless communication environment. For example, a UE repeatedly performs cell searches and signal quality measurements of cells neighboring its serving cell in order to select the cell having a better reception performance.

However, communication devices are controlled according to predetermined operation methods with respect to changes in the wireless communication environment (e.g., changes in position and/or speed). Many communication devices are controlled by only a limited logic structure (i.e., a passive logic structure) and cannot be controlled according to a variable logic structure (i.e., an active/adaptive logic structure) which considers empirical information. As such, many communication devices can only operate according to the current wireless communication environment, and cannot predict its own moving pattern or operate according to control information generated based on predicting its own moving pattern.

FIG. 1C is a diagram of a cellular communication system including UE 110 according to an embodiment of the present disclosure.

In FIG. 1C, the cellular communication system includes the user equipment 110, a central management server 150 a, and an evolved-NodeB (eNB) 160. Central management server 150 a is an example of server 150 in FIG. 1B. The central management server 150 a includes an information processor 152 and a share database 154.

Herein, an eNB such as eNB 160 may also be referred to by various terms such as an Access Point (AP), a Base Transceiver System (BTS), and the like, as would be understood by one of ordinary skill in the art.

FIG. 2 is a flowchart of a method for a communication device to control its operations by providing current environment information to a central management server according to an embodiment of the present disclosure. In the description of FIG. 2, reference will be made to FIG. 3 to provide examples of specific operations.

In the embodiment of FIG. 2, there are two types of device control information: that are generated by the communication device or a UE (“first” or “UE-generated control information”) and that generated and/or sent by a central management server (“CMS-generated control information”). The central management server generates its device control information based, at least in part, on current environment information provided by the UE. The UE uses one of the two types of device control information to control its operations. The UE-generated control information and the CMS-generated control information comprise the same types of control information (such as, e.g., an Infinite Impulse Response (IIR) filter coefficient) but may have different parameter values (e.g., “3” rather than “5” for the value of the IIR filter coefficient) from each other.

In step 200, information (e.g., one or more parameters) of a first (or current) wireless communication environment is transmitted to the central management server. In step 210, it is determined whether CMS-generated control information has been received from the central management server while in the first wireless communication environment.

Wireless communication environment parameters may be the position or transmission rate of the communication device or UE, a reception signal power (e.g., Received Signal Strength Indication (RSSI)), a signal-to-noise ratio (SNR), a maximum delay path, a Doppler frequency, timing offset, and/or frequency offset. The position of the UE may be determined by GPS or an Observed Time Difference Of Arrival (OTDOA) scheme, and the transmission rate may be measured by an accelerometer included in the UE. A first (or current) wireless communication environment parameter refers to a condition or measurement of the current wireless communication environment.

In the present disclosure, first or the UE-generated control information and second or CMS-generated control information include various parameters for controlling the communication device in a specific wireless communication environment. The parameters may be for controlling a modulator/demodulator for modulating or demodulating a received signal, for controlling a channel estimator (e.g., a Finite Impulse Response/Infinite Impulse Response (FIR/IIR) filter coefficient), and/or for performing synchronization with the eNB. However, a difference between the UE-generated control information and the CMS-generated control information is that the UE-generated control information is generated according to an operation scheme already stored in the communication device or user equipment according to the current wireless communication environment, that is, based on the limited range or limited logical structure configured by the communication device, but the CMS-generated control information is generated with reference to information including parameter having the highest index among ever-changing performance indices measured according to values of various parameters in a specific wireless communication environment.

For example, in a case in which the communication device 100 is moving at 30 km/h from a location Samsungno 129, Yeongtong-gu, Suwon-si, Republic of Korea, the value of an IIR filter coefficient according to the UE-generated control information may be 3, while the value of the IIR filter coefficient according to the CMS-generated control information corresponds to the highest performance index and may be, e.g., 5, which is determined according to a predetermined criteria, among performance indices (e.g., a tracking time for a transient state of a filter, a jitter value for a steady state, Cyclic Redundancy Check (CRC) code information, throughput information, and Adaptive Modulation and Coding (AMC) information) according to a value of each coefficient by changing values of the IIR filter coefficient (e.g., changing from 1 to 7). Such information may be stored in a database, such as the share database 154 of CMS 150 a in FIG. 1C, of the central management server.

The predetermined criteria for selecting an optimal value for the parameters or determining the priority may involve, for example, measuring a frequency for parameter values corresponding to the highest performance index and selecting a parameter value having the highest frequency, or converting the frequency to a weighted value and then calculating a parameter value using a Maximum Ratio Combining (MRC) scheme.

UE-generated control information may be pre-stored in a memory (such as, e.g., memory 103) or storage unit of the communication device 100 (and may be stored in the form of a look-up table), calculated and/or determined by the communication device 100 according to a predetermined method (e.g., calculations based on established/stored formulae) using various pieces of information received from the eNB serving the communication device 100, and/or provided by the central management server.

The CMS-generated control information may be generated in a large variety of ways, depending on the embodiment of the present disclosure. Moreover, CMS-generated control information may comprise/be generated from many different types of information. For example, when a communication device 100 initially corresponds with its specific wireless communication environment (e.g., when a performance test is performed as or before the communication device 100 is launched), the measured control information may be stored by the CMS as “history information” for generating CMS control information for the communication device 100. When CMS-generated control information is transmitted to the communication device 100, all control information stored in the CMS database may be transmitted, or only a part of the CMS-stored control information may be transmitted.

Examples of steps 200 and 210 may be described referring to FIG. 3, in which UE 300 is shown in a number of possible locations, including, for example, on moving train 302, in moving automobile 304 on a highway, or carried by moving user 306. Train 302 and automobile 304 are non-limiting examples of transportation, used here merely for convenience. No matter which means of transportation, information on the present position and current moving speed of UE 300 is transmitted to the central management server (CMS) 330 (i.e., step 200 of FIG. 2). By collectively taking the current position, the current speed, and other factors (such as, e.g., current traffic conditions where automobile 304 is located) into consideration, it is possible to predict a position (including a position in a neighbor cell 322) or a speed UE 300 will have after a predetermined time. The central management server 330 may transmit CMS-generated control information concerning the second (or next/future) wireless communication environment of UE 300 on the basis of information transmitted from UE 300, while still in the first (or current) wireless communication environment.

In step 210 of FIG. 2, it is determined whether such CMS-generated control information has been received by the communication device 100. If such CMS-generated control information is received, step 220 of overriding the UE-generated control information for controlling the communication device 100 for the CMS-generated control information (i.e., changing the CMS-generated control information to top priority) is performed, and then, in step 230, the communication device 100 is controlled according to the CMS-generated control information while in the second (or next, i.e., now current) wireless communication environment. The CMS-generated control information may include an identifier indicating the overriding function, or the communication device 100 may perform the overriding function merely because the CMS-generated control information has been received. The central management server 330 in FIG. 3 is connected to eNB 312 of serving cell 310 and eNB 322 of neighbor cell 320.

Accordingly, according to various embodiments of the present disclosure, the communication device 100 may be actually controlled on the basis of the CMS-generated control information, resulting in enhanced performance in the second wireless communication environment in which the communication device 100 is located so that performance of the communication device 100 can be improved.

If it is determined that CMS-generated control information has not been received by the communication device 100 in step 210, the communication device 100 is controlled depending on the UE-generated control information in the second/next wireless communication environment.

FIG. 4 illustrates an example where the current communication environment information is provided to the CMS by a provider server according to an embodiment of the present disclosure.

In FIG. 4, the information on the first wireless communication environment is not provided by the communication device 400, but is rather provided by provider server 440 of the provider of the means of transportation by which the communication device 400 is moving. For example, information (e.g., the position or speed of train 402 or automobile 404) on the first communication environment is provided from a GPS module (not shown) and/or various sensor modules included in the means of transportation to the provider server 440, which then transmits the information to the central management server (CMS) 430. In FIG. 4, CMS 430 and provider server 440 are connected to eNB 412 of serving cell 410 and eNB 422 of neighbor cell 420.

FIG. 5 illustrates an example in which log information is transmitted to the central management server and the priority of device control information stored in the central management server is adjusted or re-determined according to an embodiment of the present disclosure.

In FIG. 5, when communication device 100 or UE 500 is in a new wireless communication environment, it performs, in order for the CMS to decide whether to re-configure, re-determine, and/or update the priority of the CMS-stored device control information, a function/operation to provide one or more parameters by which the CMS-stored device control information is determined. When communication device 500 receives CMS-generated control information, the communication device 500 performs a function/operation to determine a parameter of the received CMS-generated control information (such as, e.g., a parameter for controlling the channel estimator), in the new wireless communication environment during a predetermined time, and then transmits the determined parameter (i.e., information on the new wireless communication environment) and log information to CMS 530. Information on the log information and the new wireless communication environment may be transmitted to the CMS 530 in a scheme such as an indexing scheme, a compressing scheme, a transform scheme, or a priority sorting scheme.

The log information may include the values of the various parameters and performance indices corresponding to the values of the parameters. Further, the log information may include various pieces of information such as cell identification information, a signal-to-noise ratio for a reception signal, timing offset, and frequency offset, Doppler frequency information, reception signal power, and channel state information.

When the log information is received, the CMS 530 may re-determine a priority according to a method of determining a pre-determined priority on the basis of a result of the performance index. The method of pre-determining the priority may be applied to the method of determining the priority described above. The performance indices may be stored in the share database of the CMS according to the re-determined priority. Like FIGS. 3 and 4, the CMS 530 is connected to eNB 512 of serving cell 510 and eNB 522 of neighbor cell 520.

FIG. 6 is a flowchart of a method in which the priority of CMS-generated control information is re-determined by the CMS according to an embodiment of the present disclosure.

In step 600, the CMS receives information on a new wireless communication environment and log information from a UE. In step 610, the CMS decides whether device control information on the new/current wireless communication environment exists in a share database of the CMS.

If device control information on the new/current wireless communication environment exists, the CMS decides whether the priority of the device control information must be re-determined in step 620. For example, when the priority, which is determined according to a predetermined criteria, of a performance index transmitted from the UE is different from a priority of the device control information stored by the CMS, the priority of the device control information is required to be re-determined in step 620. If the priority of the stored device control information is to be re-determined, the CMS re-determines the priority of the device control information stored in its database in step 630. If the priority of the stored device control information is not to be re-determined, the priority of the device control information stored in the CMS database is maintained, that is, there is no change of the priority, in step 640.

After re-determining the priority of the device control information stored by the CMS in step 630, it is determined in step 650 whether the predetermined time to perform a function/operation to determine the new control information based on the re-determined priority has expired. If the predetermined time has not expired, the CMS transmits the new device control information, which is of a type different from the type of the device control information previously transmitted to the communication device 500, in step 660. Through step 660, the communication device 500 may perform a function or an operation in which device control information is determined even for the type of control information which the CMS share database does not have.

The term “module” as used herein may, for example, refer to hardware, software, firmware, and/or a combination of two or more of them. The term “module” may be used interchangeably with, for example, the terms “unit”, “logic”, “logical block”, “component”, or “circuit”. A module may be a minimum unit or a part of an integrated component element or a minimum unit or a part of a component for performing one or more functions. A module may be mechanically, electronically, and/or software implemented. For example, a module according to the present disclosure may be any one or more of an Application-Specific Integrated Circuit (ASIC) chip, a Field-Programmable Gate Arrays (FPGA), and/or a programmable-logic device for performing operations which are presently known or are developed later.

According to various embodiments, at least some of the devices (for example, modules or functions thereof) or the methods (for example, operations) according to the present disclosure may be implemented by commands, instructions, routines, programs, and the like stored in a non-transitory computer-readable storage medium. Such stored instructions, when executed by a controller, control module, or the like (such as, e.g., processor 102), causes functions corresponding to the instructions to be performed. The non-transitory computer-readable storage medium may be, for example, memory 103.

The non-transitory computer readable recoding medium may be one or more of a hard disk, a floppy disk, magnetic media (e.g., a magnetic tape), optical media (e.g., a Compact Disc Read Only Memory (CD-ROM) and a Digital Versatile Disc (DVD)), magneto-optical media (e.g., a floptical disk), a hardware device (e.g., a Read Only Memory (ROM), a Random Access Memory (RAM), a flash memory), and the like. In addition, the program instructions may include high level language codes, which can be executed using an interpreter, as well as machine codes made by a compiler from language codes. The aforementioned hardware device may be configured to operate as one or more software modules in order to perform one or more operations of the present disclosure, and vice versa.
